FIG. 6 is a plan view of a water-activated hair removal sheet according to still another embodiment of the present invention. Hereinafter, the present invention will be described in detail with reference to the drawings.

成されている。Each of the water-activated hair removal sheets 10 shown in FIGS.
In FIG. 1, an adhesive layer 12 containing a film-forming polymer and a depilatory drug is formed on a support 11 in the form of a sheet or a film.

糊のこりを生じてしまう。The support 11 must have hydrophobicity. Here, the term "hydrophobic" refers to a substance having a low affinity for water, that is, a substance having a small hygroscopicity (water absorption), and excludes a substance that easily absorbs water such as a cloth such as a cotton cloth. That is, in the case of a material having a hydrophilic property, such as a cloth, the water used for pasting on the skin surface is absorbed by the support 11 so that it is difficult to obtain a proper adhesiveness and a proper pH, and the support 11 absorbs the water. It is necessary for the water to evaporate, which requires a drying time. As a result, the adhesive layer is peeled off in a state where the adhesive layer is not sufficiently dried, and a residue of the coating film on the skin surface, that is, glue residue occurs.

によって得ることができる。[0023] Among the above-mentioned depilatory drugs, thioglycolic acid and salts thereof accelerate the decomposition rate of keratin under alkaline conditions and exert their effects effectively. Therefore, when the drug is used, it is desirable that the drug be alkaline under humid conditions. For this reason, it is desirable to mix a basic substance in the adhesive layer 12. As this basic substance,
For example, sodium hydroxide, calcium hydroxide, triethanolamine and the like can be mentioned. The amount to be blended varies depending on the basic substance used, but it is desirable to blend so that the pH of the adhesive layer 12 of the final product is 9 to 13, preferably 10 to 12. By adjusting the pH within this range, a suitable pH for the depilatory drug can be obtained when it is wetted to such an extent that it can be appropriately adhered to the skin surface according to a normal use method as described below. On the other hand, when the pH exceeds 13, the skin irritation is increased, which is not preferable. The pH was determined by dissolving the adhesive layer 12 in water and adding 10% by weight.
An aqueous solution can be obtained by measuring with a commercially available pH meter.

きる。The water-activated depilatory sheet 10 according to the present invention can be produced as follows. An appropriate amount of water or / and a hydrophilic medium and various other additives are added to the above-mentioned film-forming polymer or depilatory drug and, if necessary, mixed well to prepare a coating solution, and the coating solution is desired. It is applied on process paper to such an extent that a sticking layer 12 having a thickness is obtained. Then, the support 11 is laminated and dried sufficiently, and the support 1 is dried.
An adhesive layer 12 is formed on 1. At this time, when the support 11 made of a nonwoven fabric is used as described above, a part of the support 11 is preferably buried in the adhesive layer 12. When a part of the support 11 is buried in this way, the anchoring force between the support 11 and the adhesive layer 12 is improved, and the peeling residue (film) after peeling can be further reduced.

Further, as described later, a separator 13 may be laminated on the sticking layer 12 as necessary. When the separator 13 is used, a coating liquid is applied directly on the separator 13 to form the sticking layer 12. It can also be formed.

Alternatively, the water-activated depilatory sheet 10 is applied after applying an appropriate amount of water or the like to the application site. At this time, the adhesive layer 12 is once wet or dissolved by the applied water or the like, and the film-forming polymer is uniformly entangled in the body hair. The keratin in the body hair is dissolved by the hair removal drug dissolved by the applied water or the like, and the body hair is cut. In this manner, the cut hair is taken into the dried coating and is removed together with the support 11 and the coating. As described above, the hair can be easily used at the time of use, and the hair can be removed in a relatively short time without leaving any peeling residue.

For this reason, at the time of peeling, it is necessary to peel off the attached depilation sheet 10 with a nail or the like, and there are cases where the sticking layer 12 adheres to the skin surface and is difficult to peel off,
Sometimes nails can hurt the skin surface. Therefore,
A grip portion 14 in which the adhesive layer 12 is not formed on the support 11
It is convenient to provide

The grip portion 14 can be easily provided by applying only a predetermined region with a coating solution composed of the film-forming polymer, the depilatory drug, or the like. By providing the grip portion 14 in this manner, the portion of the support 11 that does not adhere to the skin surface can be left, and the support 11 can be easily gripped without peeling off with a nail or the like. Therefore, the epilation sheet 10 can be easily peeled off without damaging the skin surface.

Depending on the composition of the adhesive layer 12, the water or the hydrophilic medium used in the production process cannot be sufficiently evaporated, and the adhesive layer 12 may be slightly tacky. In this case, the separators 13 are stacked from the viewpoint of storage and the like. The separator 13 is not particularly limited as long as it is widely used as the separator 13 of a general adhesive material. For example, polyester, polyethylene, a plastic film such as polypropylene, a metal film such as an aluminum foil, and the like. Various films and sheets can be used. In addition, high quality paper, glassine paper, parchment paper, or high quality paper obtained by laminating polyethylene or the like on these release papers may be used.

施できる。The separator 13 is formed not only on the adhesive layer 12 but also larger than the adhesive layer 12 in consideration of the ease of peeling, and is designed to protrude above the grip portion 14. At this time, it is desirable that the packaging material does not become larger than the support 11 so as not to be unnecessarily large. Therefore, at the time of peeling, the protruding portion can be provided, and the cost can be reduced.
